【沉浸式学习】

一.连词概况

1.定义：连接单词、短语或句子的虚词叫做连词

2.分类：并列连词（常见的 and/but /or....）和从属连词（that/when/which/where/whose/what...）。并列连词即连接两个不相互依附且意思同等重要的句子；从属连词即连接三大从句（定语从句、状语从句、名词性从句）的连词

二．并列.连词精析

 

【前方高能区】　when可用作并列连词，相当于and at this/that time，意为“正在这/那时；突然”，常用于下列句式：sb be about to do/going to do/on the point of doing sth when...(某人正要做某事，突然……)；sb be doing sth when...(某人正在做某事，突然……)；sb had just done sth when...(某人刚做完某事，突然……)。

【例句鉴赏】

He was about to go out when it rained.

他正要出去时，这时下雨了。

He had just arrived at home when the boss let him type a letter.

他刚到家，老板就让他打印一封信。

【活学活用】　

I.单句语法填空

1.Boxing Day is a National Bank Holiday，a chance to eat your leftovers _________watch TV. and

2.“Children did not create this conflict, _________ they are its greatest victims.   but

3.It’s never been so important to spend time outside, __________that’s because it’s the only place to experience different cultures.   and

【解题妙招】

1.分析句子成分

如果设空处前后两部分都有独立的主谓结构(或有祈使句)，前后两部分又不缺少句子成分，且前后两部分不存在从属关系，则设空处一定填并列连词。

【典例】　The data is based on more than 491，000 older adults who used home care between 2007 and 2013________is focused on people who are likely to die within the next five years.

解析　句意：这个数据是基于2007年至2013年使用家庭护理的超过491 000个老年人并关注了那些极有可能5年之内死去的人。设空处前后两部分是并列的谓语is based on和is focused on，且此处表示并列关系，
